In New York, the demand for bus tickets caused delays on Greyhound buses destined for the march.

A total of 18 extra Greyhound buses were added to the 3:45 a.m. schedule, but the short notice meant some buses didn't get drivers on time. A Greyhound spokeswoman said the buses left by 6:30 a.m. and there were no further delays. Demonstrators said there were postponements on Peter Pan as well. The bus company didn't respond to a call seeking comment.

In Maryland, Rose Wurm got on her bus at 7 a.m. in Hagerstown, ready for the ride to Washington.

The 64-year-old retired medical secretary from Bedford, Pennsylvania, carried two signs. One asks President Donald Trump to stop tweeting. Another asks him to fix ex-President Barack Obama's health care law, rather than get rid of it.

'I Can't Even See the End of the Crowd!': Michael Moore

Cripe and Wurm were riding two of the roughly 1,800 buses that registered to park in Washington on Saturday. That translated into nearly 100,000 people coming for the march just by bus.

One company had buses coming from more than 200 cities in 26 states. It was using school buses to bring people to the march from Maryland.

In the air, a Southwest flight full of women flying to Washington lit up with pink lights in the cabin in apparent solidarity with the passengers.

"When your Southwest flight crew celebrate a plane full of kicka-- women and men going to the Women's March by lighting it up!! #lit #womensmarchonwashington #lovetrumpshate," passenger Krystal Parrish wrote on Instagram with a picture of the light pink hues.

In a statement, Southwest Airlines said the lighting was not a company-wide initiative, but that crews on flights sometimes adjust lighting based on passengers aboard.

"Some of our aircraft are equipped with mood lighting and while this was not a company-wide initiative, at times, our flight crews will adjust the lighting for a customer or group of customers traveling on their flight," the statement said. "For example, in October, one of our Flight Crews changed the lighting to honor a breast cancer survivor on board their flight."

A passenger on a flight from Chicago to Baltimore Thursday called the light adjustment was a welcome surprise.

'Do Not Try to Divide Us': Steinem at DC Women's March

Gloria Steinem spoke at the Women's March in Washington, DC, amidst a foggy sky and thousands of people wearing pink hats. "This is the upside of the downside," she said gesturing to the crowd. "This is an outpouring of energy and democracy like I have never seen in my very long life."

"It was unexpected and unannounced," passenger Jennifer Moran told NBC in an email. "There was no announcement explicitly from the staff and no one screamed this is for the march. Nothing, just spontaneous and everyone knew exactly why they were cheering."

By early Saturday morning dozens of others had shared photos and videos on social media showing passengers celebrating en route to the march.

In one video posted to Twitter, a flight attendant was heard welcoming passengers to Baltimore and requesting a round of applause for all the "nasty women" attending the March on Washington. She then reminded them to stay hydrated and to remember that "we don't take no ish from no man."
